    Reminds me of the old saying... "do you really hear what you are saying?".  Or as I'd put it, "do you really hear what you are saying or are you really that stupid?" :)

    Steve

    Can't find the meme picture now, but the idea was roughly

    (Russia, knocking on door) "Let me in"
    (Finland) "Why?"
    (Russia) "I'm going to protect you"
    (Finland) "Protect me from what?"
    (Russia) "From what I'm going to do to you if you don't let me in"

    First thing I thought of when I saw quotes of Lavrov was "gee, I wonder if the Israelis will think a bit harder about their relationship with Putin".

    Steve

    Kind of wish they gave more air time to Latrinov in the western media -- giving him more rope to hang himself with that is ...

    Older inertial guidance was subject to a lot of drift. On the order of 4 Nautical Miles per Hour was considered quite good.

    Update systems were required for many of them. Celestial, navaid, radar, etc., to return the drift to a known position.

    For a Soviet-era SRBM of the 60's/70's, meant to be equipped with a nuclear warhead, the drift would certainly be acceptable without the added expense of update systems or high-accuracy inertial nav systems.

    The old "horse shoes and hand grenades" statement...

    Modern ring-laser gyros, coupled with modern solid-state accelerometers produce accuracy several (3, 4, or 5) orders of magnitude better than the old "spinning mass" systems.

    Thanks for the info! Didn't know the accuracy was quite that bad, although I was aware of some ballistic (not cruise) missiles using also celestial navigation.

    Well, that might explain some of the wide misses that have been noted.  IIRC back in those days guidance was all based on estimated times for it to get from A to B.  The missile would stay on a fixed compass heading for that amount of time then change paths to another heading for another predesignated amount of time.  Time per leg could be adjusted inflight by comparing actual airspeed to what was used in the calculation, either decreasing or increasing as needed.  If this sounds pretty iffy to you... correct!  This is why they tried to fly these things in straight lines and as few as possible.

    At least that's how I remember this old stuff.

    Steve

    Well, certainly not an expert, but I would guess inertial guidance instead of simple dead reckoning?

    No, judging on display this is Stugna-P, just missile was lauched from upper storeys of the modular building  

    One thing I've been wondering is -- since Stugna-P is laser guided AIUI -- we're seeing very few vids of tanks popping smoke. Don't RF tanks have detectors, are they only facing forward, or is it just operator ineptness?

    In CMBS smoke popping and reversing happens the instant someone points a laser a tank's way ... BFC please fix or something 😄

    Thanks for that.  It is the obvious move for Russia.  Thankfully the Russian senior commanders do not appear to know about the German's Operation Zitadell that was fought not too far from the area.  Because if they did, they would maybe try to do something else.  Giving the defender time to reinforce forces along obvious attack paths is not generally a good thing, but especially if the attacking forces have a bad track record of attacking.

    I think I know where the Slovak S-300 system is going :)

    Steve

    In keeping with that Zitadelle theme, they should delay for a month or two just to get those Armatas to participate 😛

    A little number juggling for fun :
    In 2020 :
     
    🇺🇦 UKR spend 6 B $ in military. GDP = 155 B $ = 3.8 % in military

    🇷🇺 RUS spend 67 B $ in military. GDP = 1483 B $ = 4.5 % in military (how much corrupted is a good question 😁)

    🇺🇸 USA spend 766 B $ in military. GDP = 20 936 B $ = 3.6 % in military

    So 300 M $, it's a 5% bonus for UKR of it's military expenditure and only 0.04% of US military expenditure.

    I haven't keep track of all assistance since the beginning of the invasion but I wouldn't be surprise there is a at least 50 % bonus expenditure for UKR.

    source Trading economics


     

    Another nice bonus is the donations from people all over the world to the armed forces of Ukraine. I was wondering how it was going and was happy to see this update:

    Nearly UAH 13.7 Billion Transferred for Needs of Military, over UAH 619 Million Remains in Special Account

    If I did my currency conversion correctly 13.7 billion UAH is 460 million USD.

  8. Did not see this mentioned yet. Lawyers are getting involved ...

    12 Rosgvardia troops that refused to participate in the invasion were fired from their jobs; their lawyer is now arguing there is no basis for the sacking, as officially Russia is not at war.

     There shouldn't be any alpha emitters in the dust/soil around Chernobyl.

    Hi Ultradave,

    asking for a bit more detail here. It's been decades from my last physics class but living in an area where radon can be a problem keeps you at least somewhat aware of radioactive decay ... no significant alpha emitters?

    AIUI U-235 is used in reactors and it decays to thorium via alpha decay (and there's plenty more alpha decay on the path down to lead, e.g., radon) but it takes aeons to do so, so unless there is massive amounts of it around there's not much alpha floating around. right? I would still avoid kicking up uranium dust, if not for anything else but for the toxic effects 🙂

    As if this Russian troops withdraw from Chernihiv oblast

     

    Reportedly about one Russian BTG is in semi-encirclement in Peremoha village area on Brovary direction, Kyiv oblast. This is several kilometers west from recently libarated villages Lukyanivka and Rudnytske. Russian troops are almost out of fuel and food, every day they under fire. Many of personnel as if want to surrender, but commanders tried to force them to fight until supply and reinforcements will not arrive

    Start offering cash prices for incapacitated commanders delivered to you when surrendering?

    Some about Russian gears... Here captured Russian recons. Four men. One dead, other probably wounded or just surrendered. This guy was captured barefoot - probably he had gumboots and lost them in the mud, when runinig away across the field. Instead the socks he has footcloths (rus. "portianki")

    BMP-2 on background is Ukrainian.

     

     

    I used foot rags in my Finnish army service in the early 90s. Quite comfortable in boots as long as you fold them properly.

    Yeah my bad  - I caught the capital "S" and assumed

    Yeah I was talking about this lovely guy, https://www.politico.eu/article/outrage-germany-ex-chancellor-schroder-gazprom-board-nomination/

    My country has an ex-prime minister on Nord Stream payroll as well, so it's not only Schröder, but it's just disappointing to say the least. Either they are corrupt, or useful idiots. In either case they should never have been political leaders.

    Germany uses gas for more than just heating purposes though - There is a lot of industrial use of natural gas - so cutting off gas supplies will mean shutting down of  parts of the German industry and all the subsequent knock on effects that come out of that .

    All the more reason to have more than one supply then. Apparently Germany doesn't currently even have a LNG terminal for shipborne imports? Great planning there.

    Schröder must have got an absolutely massive bribe. Or he's a massive idiot. Or both.

    The forces there are NOT cut off.  The supply lines are difficult, but they exist.

    Here's a map that appears to be more accurate than some of the ones out there:

    Apologies if this a repeated topic -- I have read through the whole thread but probably forgotten half of it 🙂

    How should we read those Russian tendrils spreading out? Advances along major roadways, obviously, but how much actual control of the area that represents?
    A unit at the head of advance and garrisons strung along, every village and crossroads perhaps? And convoys doing Mad Max runs from garrison to garrison? Or something more solid?

    Can the Ukranians do a Raate road repeat and cut the red snakes into pieces to be defeated in detail? Or do they also suffer from too much rasputitsa-related movement restrictions outside of the roads for that not to be possible?

    Group of Russian troops of 138th motor-rifle brigade (Kamenka town, Leningrad oblast, Western military district) tried to dig-in in the tree-plant and hold the ground, but something went wrong.... 3 MTLB, 1 T-72B3 and Metis (or Metis-M) ATGM.

    It's been mentioned multiple times in the local news in Finland that the Russian garrisons along the border have been drained of combat troops, at least every two out of three battalions committed to Ukraine.

    Some journalists went to interview locals last week, but were asked to leave soon. But not before getting an admission from an officer's wife that the soldiers knew where they were heading, and rumors of 350 wounded for the Kamenka brigade (article only in Finnish unfortunately https://www.hs.fi/ulkomaat/art-2000008665103.html )
